Weblog:   Graying MySQL, and MySQL learns a second language (early conference report )
Subject:   MySQL is to DW what PostgreSQL is to OLTP

Response to: MySQL is VHS to Postgresql's Beta though

I agree with you fifty percent, merlyn. PostgreSQL is the clear choice over MySQL for any sort of OLTP. Only now is MySQL adding features which are needed for OLTP.


However, those same features are of little or no value to MySQL as a DW platform--they're cruft. Why in the world would a properly designed data warehouse require triggers?


I understand why every RDBMS is now adding such featurs--after all, Oracle has them, so everyone else needs them, too. I wouldn't use Oracle for a DW on a bet, though. It's not capable of scaling to a sufficient size for a large enterprise, and it's not a good vslue for a smaller business. I do understand why MySQL, partnering with SAP, might feel the need to match Oracle feature for feature.


That's a shame. MySQL is built nicely for high performance in the DW space. Adding views was absolutely necessary, and even updatable views have their place. (Last year, I had to use updatable views to get around an incredibly stupid, incredibly popular etl product's inability to do what we needed.) But most of what MySQL has picked up in database features is unuseful for DW.

    What???

    Can you elaborate on that statement? What do you mean by scale in that context?
